EDWARD W. GERRISH, OF LYNN, MASSACHUSETTS.

LAST.

Specification of Application filed April 26,

To all whom it may concern:

Be it known that I, EDWARD 1V. GERRISH, a citizen of the United Statesof America, and a resident of Lynn, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inLasts, of which the following is a specification.

This invention relates to lasts, particularly to divided lasts connectedtogether by a hinge, and having aportion of the hinge cut away to permitthe shortening of the last when the heel part is moved about the hingepivot toward the fore part.

The particular object of the invention is to provide a simple hinge ofgreat strength which may be manufactured very cheaply, and it consistsin positioning within a transverse opening in the fore part acylindrical member having a diainetrical threaded opening therein, inwhich is positioned the threaded end of a bolt mounted in the heel partand extending through a vertical slot communicating with the saidtransverse opening.

The invention further consists of a looking bolt adapted when the lastis lengthened to extend through an opening in the fore part and into arecess in said cylindrical member.

The invention further consists in a spring pressed tubular plug mounted=-in a recess in the fore part with its outer closed end rounded andbearing against the front face of the heel part.

The invention further consists in providing the fore part with aprojection in which the hinge plug is mounted, having a face slightlyeccentric to the center of said plug, so that when the last is shortenedby moving the heel part about the hinge pivot, the contacting face ofsaid heel part will bind on said eccentric face and retain it in suchadjusted position.

The invention further consists in certain novel features of constructionand arrangement of parts which will be readily understood by referringto the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a longitudinal vertical section ofa last embodying the features of the present invention, Fig. 2represents a similar view of t e" same, showing the heel part moved intopo- Letter n Patented Oct. 31, 1911'.

being on line 33 on Fig. 1, Fig. 4: represents a horizontal section of aportion of the last, the cutting plane being on line H on Fig. 1, andFig. 5 represents a diagrammatical View showing the eccentricity of theprojection on the fore part, in which the hinge plug is positioned.

Similar characters designate like, parts throughout the severalfiguresof the drawings. l I

In the drawings, 10 and 11 represent .respectively a fore part and aheel part of a separated as indicated at 12. rear face of the fore part10 is a projection 13, through which extends a cylindrical transverseopening 14:, in which is centrally positioned a cylindrical metal plug15 of less length than the opening 1a. This plug 15 is revoluble withinsaid opening 14, and when positioned therein the ends of the opening 14are closed by wooden plugs 16 glued therein and having their ends formedto conform to the shape of the last. The projection 13 has a curved face17 slightly eccentric to the axis of the opening 14:, one

tending slightly beyond the end portions thereof, as clearly indicatedin diagram in Fig. 5 of the drawings. This projection 13 front face ofthe heel part 11 as indicated in Figs. 1 and 2 of the drawings. Theprojection 13, with its eccentric curved face 17 on the fore part 10,and the concaved recess of the heel part 11, in which said prolast isbeing sawed to divide it. The outer portion of the projection 13 isprovided with a vertical slot 18 communicating with the transverseopening 1 1. The heel part 11 has bored therein, longitudinally thereof,a cylindrical hole 19, communicating with a ing a shoulder 21.Positioned within the which projects beyond the front face of the heelpart 11, throughthe vertical slot 18, and is threaded to'a diametricalthreaded opening 23 in the plug 15. The head 24 of jhe'bolt 22 bearsagainst the shoulder 21, and by turning the bolt 22 the fore part 1Q andheel part 11 may be adjusted relative to sition to shorten the last,Fig. 3 represents a each other to produceithe required amountlast, theupper opposing faces of which are jection is positioned, are formed whenthe opening 19 is a bolt 22, the threaded end of horizontal sectionaldetail, the cutting plane I portion thereof intermediate its ends'exfits into a concaved recess formed in the larger cylindrical hole 20in alinement therewith, the inner end of the hole 20 form- 70 From thethe bolt 22 by inserting into the larger hole desired to shorten thelast.

20 a loose plug 25 against the outer end of which is inserted an outerplug 26, which is glued imposition and has its outer end finished toconform to the ,shape of the last. By this construction of a hinge avery rigid connection is made between the fore part and the heel part ofthe last, which has great strength, and is wholly inclosed so that itsparts icannot, under any circumstances, become displaced.

Should contacting surfaces become worn to any extent so that thefrictional contact between the two parts of the last is insufii? 1 cientfor'the proper operation thereof, the plug 26 may be bored out, theloose plug 25 removed, and the bolt 22 adjusted to re new the frictionalcontact. After this has been accomplished, the loose plug 25 is returnedinto the opening 20 and a new plug 26 is inserted and secured inposition. In a vertical hole in the front end of the heel part 11 ismounted a locking bolt 27, the lower end of which normally extendsthrough an opening 28 in the projection 13, with its extreme endpositioned within a pheriphcral recess 29 formed in the plug 15. Theupper end of the bolt 27 is surrounded by a staple 30, between which and'a shoulder on said bolt 27 is interposed a spring 31, normallyretaining the bolt 27 in the position indi? cated in Fig. 1 of thedrawings. The up per end of the bolt 27 is provided with a thumb piece32'by' which the bolt 27 may be withdrawn from the recess 29 and fromthe hole- 28 to permit the movement of the heel part 11 about the pivotof the hinge when it is During this shortening operation the end of thebolt 27 rides along the curved face 17 of the projection, 13, asindicatedin Fig. 2 of the draw-' ings. "When the ,heel part 11 isreturned to its norma'l position, as indicated in Fig. 1, the spring 31will operate to cause the bolt 27.to again enter the hole 28 and therecess 29, and the two parts 10 and 11 will again be locked inposition.- This return movement ofthe' heel part 11 to its normalposition is assisted by the hollow'spring pressed plug 33, the outer endof which is rounded to press against the front face of the heel part 11,while its opposite openend is inserted in the hole or recess 34 formedin the fore part 10. A spring 35 is mounted in the hollow plug 33 andthe hole 34, and as soon as the heel part ll'has been moved sutlicientlyfar to pass the eccentric portion of the projection 13, the operation ofthe spring 35 will complete the movement of the heel part 11 about thehinge pivot until it has reached its normal position. This makes a veryeflective last which is simple in its construction, and has itsoperating parts all entirely inclosed and protected from any foreignsubstances which might interfere with their operation. a

It is believed that the operation and many advantages of the inventionwill be thoroughly understood without any further description.
